I have 2 of these and 4 of the monofacial. They all put out right around what they're supposed to. Bifacial, of course, does a bit better. This is a great price, even better than the deal I posted a few weeks ago.

I'm getting 2 more to complete 2 parallel strings of 48V.

Better deal if you buy 2 and use code CDUS08 for $8 off.

And yes, I trust AliExpress, like I said I have 6 panels from them already and they all work perfectly fine. Only mentioning for those that are on the fence about buying from AE, cuz I know there are a lot of AE haters out there. And no, I'm not a shill.

Serial is not ideal if you have shading. Parallel works better. If you have 4 panels in a series and 1 panel is partially shaded, the entire string is held back by that 1 panel. Since at the combined voltage, it'll only output the number of amps that shaded panel can put out. Which isn't much. You can increase output by fully covering that shaded panel so that it drops out and the charge controller adjusts to the lower voltage. With parallel that doesn't happen. The other 3 panels will still be going full bore. So I parallel when I can. Serial only if I have to.

The 100w panels keep getting cheaper and cheaper. I'd like to see larger panels come down like this.

They're just the economical choice, not the best 100w panel. I am planning on buying some in case of power outage during hurricane season this year, like 4-6 of them.

I bought 3 of the monofacial and they work as they should. The glass was completely cracked throughout on one and the seller offered a replacement. I haven't receive the replacement yet but its only been 4 days.
I ordered 4 of these bifacials just now.

My experience with eco-worty panel is other way around, they don't come close to there rated wattage.
They are close to 76% of rated power, have gone though a year with them.

If I have solar panels already installed on my home, could these be hooked up to the system to add more energy generation? Or would they be incompatible somehow?

I have had Ecoworthy 100w panels on my camper van for a few years. No complaints.

Wow... around black Friday I got the Renogy 400W Portable Solar Panel Blanket for $380. Some reviewers claimed they slightly exceeded in direct sunlight, but I never got a chance to test that case.


I shouldv'e saved my money and got these instead. But to be fair, the Renogy is 16lb while one of these panels is 14.5lb, so there is that difference.

I wonder about their durability though. 25 years would be great but I'd want to be sure before installing on a roof (unless you're a DIY knowing what you're doing). Anybody here have them for years?

Best to have someone familiar with solar to take a look at your system. It might work if installed properly, or it might be totally incompatible, depending on what you have.

You'll have to see if your system is compatible voltage and charge controller

I was worried when I bought these a few weeks ago that they would come destroyed somehow. They are simply packed well.

Aren't 48v panels becoming more common? I got the impression they were a better choice for most residential applications since you didn't have to series them to get a better voltage
